PS: I have build libmusicbrainz v4 and v5 as some apps need older version of libmusicbrainz. As for now there is libmusicbrainz(v2), libmusicbrainz3, libmusicbrainz4 and libmusicbrainz5; total of 4 different version of libmusicbrainz that can be install along side together. With this changes of libmusicbrainz, some applications' dependencies list may need to be change. Let me know if anyone having problem with libmusicbrainz or apps that depend on it and I can help to update or rebuild it again.
